Traffic Management Plan vs Traffic Guidance Scheme: What's the Difference?

The difference between a traffic management plan vs TGS comes down to scope. A traffic management plan (TMP) is the overall strategy for managing traffic, cyclists and pedestrians across a project. A traffic guidance scheme (TGS) is the site-specific diagram showing exactly where signs, devices and controllers go for one layout. Most TMPs contain or reference one or more TGSs.

People mix the two up all the time, including in tender documents and permit conditions. This guide sets out what each document does, when you need one or both, who prepares and approves them, and how to keep them aligned on site. It is general guidance only: both documents must be prepared by suitably qualified people for the actual job.

The short answer: strategy vs diagram

The simplest way to remember it:

• The TMP answers how and why: how traffic will be managed for the whole job, what the impacts are, what approvals apply, who is responsible and how the public will be told.
• The TGS answers where and what: where each sign, cone, barrier, arrow board and controller goes on the road for a specific layout.

A road crew on the day mostly works from the TGS. The project manager, council and road authority mostly assess the TMP. Both need to say the same thing.

Side-by-side comparison

Terminology varies by state and organisation. Some projects call the overall document a construction traffic management plan; some councils say traffic control plan when they mean a TGS. Always read what the permit or contract actually asks for, not just the title.

What goes in a traffic management plan

A TMP should give anyone reviewing the project a clear picture of the traffic risk and how it will be controlled. Typical contents include:

• Project description: location, scope, duration, working hours and stages.
• Road and traffic context: road classification, speed limits, traffic volumes, public transport, cyclists, schools, hospitals and key access points.
• Impact assessment: expected delays, queue lengths, lost parking, changed access for residents and businesses.
• Traffic management strategy: which methods will be used and why (for example lane closures overnight instead of a daytime closure), and options considered.
• Staging: the sequence of works and which TGS applies to each stage.
• Pedestrian and cyclist management: footpath closures, detours and accessible routes.
• Heavy vehicle and plant movements: site access, deliveries, reversing and loading.
• Emergency services access: how ambulances, fire and police get through or around.
• Approvals and permits: road occupancy licences, council permits, speed zone authorisations.
• Communications: notifying residents, businesses, bus operators and the public, including VMS messages.
• Roles and responsibilities: who designs, implements, inspects and can authorise changes.
• Monitoring and review: inspections, incident reporting and how the plan will be updated.
• The TGSs: attached or referenced by number and revision.

On larger state road projects in NSW, traffic management documentation is commonly required with the Road Occupancy Licence application; our guide to the Road Occupancy Licence explains that process and its lead times.

What goes in a traffic guidance scheme

The TGS is the practical drawing. It shows the road and the work area, every advance warning sign in position, tapers and delineation, buffer zones, traffic controller and device positions, temporary speed zones and pedestrian routes, along with notes on when the plan may be used.

The sign spacing, taper lengths and buffer lengths shown on a TGS are not chosen on the day. They come from the applicable standard or guide for the road's speed and layout, and a suitably qualified person designs them. Our full explainer on what a traffic guidance scheme is covers the contents and common layout types, and how to read a TGS explains the symbols and dimensions.

When you need a TMP, a TGS or both

There is no single national rule for this. The requirement comes from the road authority, the council, the principal contractor and the risk of the work. As a guide:

Who prepares and approves each document

Both documents need people with the right qualifications and experience.

• TGS: must be prepared by a suitably qualified person. In NSW that generally means someone trained and carded through SafeWork NSW to prepare work zone traffic management plans (the PWZTMP qualification). Other states have their own designer accreditation.
• TMP: is often prepared by a traffic engineer, traffic management designer or the project's traffic manager, depending on the size of the job and the client's requirements.
• Approval: whoever controls the road or the site. That may be a council, the state road authority (for example Transport for NSW or Queensland Transport and Main Roads), the principal contractor, or several of them.

Standards matter too. Nationally, plans are designed with reference to the Austroads Guide to Temporary Traffic Management (see AGTTM explained and austroads.gov.au) and AS 1742.3, with state supplements. In NSW, Transport for NSW replaced the TCAWS manual with TS 05492:1.0 Traffic Control at Work Sites on 25 June 2026; councils and contracts may still reference older documents, so check which one your project specifies.

Other plans you may see alongside a TMP

On bigger projects the TMP and TGSs are often accompanied by other traffic-related documents. Names vary between clients and states, but the common ones are:

• Vehicle movement plan (VMP): shows how trucks, deliveries and plant enter, leave and move around the site, including turning paths, reversing areas and where spotters or traffic controllers are needed at the gate.
• Pedestrian management plan: sets out how people on foot, including people using wheelchairs, prams or mobility aids, will be kept safe and given a usable route past the work.
• Traffic management strategy: on some projects a short, high-level document agreed early with the road authority, describing the overall approach before the detailed TMP and TGSs are drawn.
• Detour or diversion plans: for road closures, showing the signed alternative route and how it will be managed.

These documents should all agree with each other. If the VMP sends trucks through a gate that the TGS shows as a closed footpath, someone will be put at risk. Whoever controls the project should make sure one person or team owns the whole set and checks them together whenever any one of them is revised.

How the two documents work together on site

On a well-run job, the TMP and TGSs are tightly linked:

1. The TMP lists every TGS by number and revision, and says which stage, shift or condition each one applies to.
2. The crew's daily paperwork references the TGS in use, so there is a record of which layout was on the road.
3. Inspections at the start and end of each shift, and at suitable intervals during it, check the site against the TGS.
4. If the site needs to change beyond what the TGS allows, the TGS is revised by a qualified person and, where needed, re-approved; if the change affects the strategy, the TMP is updated too.
5. Superseded revisions are withdrawn from site so nobody sets out an old layout.

The WHS side connects here as well. Work on or next to a road used by traffic is high-risk construction work, so a SWMS is required before work starts, and it typically names the TGS as a key control. Our guide to SWMS for traffic control covers that link.

Common mistakes that cause delays or unsafe sites

• Submitting a TGS when a TMP was required (or the reverse). Read the conditions and ask if unsure.
• TMP and TGS disagree. The TMP says night works; the TGS notes say day use only. Reviewers spot this immediately.
• Generic TMPs. Copy-paste plans that don't mention the actual bus routes, schools or driveways on the street get sent back.
• Forgetting pedestrians and cyclists. Both documents should show how people on foot, in wheelchairs and on bikes get through.
• No revision control. Several versions of the same TGS circulating by email, with the wrong one on the ute.
• Late applications. Approvals and occupancy licences take time. Build the lead time into the program, not the week before.

Next steps

If you are a builder or project manager, ask your traffic control provider which documents your job needs, who will prepare them, and what approval lead times apply before you lock in dates. For traffic control companies, TrafWise helps keep the current TGS and SWMS attached to each shift so the crew signs off on the right documents before work starts.
